RAILROAD-TIE.

SPECIFICATION forming part of Letters Patent No. 515,551, dated Febmary27, 1894.

Application filed July 21, 1893- Serial No. 48L1 N mod l-l T0 whom itmay concern:

Be it known that I, ADOLPH O. PETZMAN, a citizen of the United States,residing inzthe city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in Railroad-Ties, whichimprovement is fully set forth in the following specification andaccompanying drawings.

My invention consists of a railroad tie formed as herein described andclaimed of two frames which may be separated in longitudinal directionto introduce and remove the rails, and which when closed serve tosupport the rails in a firm and substantial manner, the tie being alsostrong and durable in its nature.

Figure 1 represents aperspective view of a tie embodying my invention.Fig. 2 represents a longitudinal section thereof, on line so, or, ofFig. 1. Fig. 3 represents a transverse section thereof on line y, 1 Fig.1.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings: A designates two frames, one being composedof the side or longitudinal piece B, and the end or transverse pieces 0,and the other composed of the side or longitudinal piece D, and the endor transverse pieces E, E. Each piece 0 of one frame is parallel with apiece E of the other frame, and in the upper faces of the adjacentpieces are recesses F, F, each corresponding to one-half of the width ofthe flange of a rail, so that the rails may be seated on the pieces 0,E, in said recesses F, the upper walls of said recesses serving as cheekpieces to embrace said fianges.

G designates bolts which are passed through the pieces C and E, and areprovided with nuts H for tightening purposes. It will be seen that whenthe nuts H are unscrewed or loosened, the pieces 0 and E separate, andthe flanges of the rails may be properly seated or located, after whichthe bolts or nuts are screwed-up, whereby the pieces 0 and E closeagainst the rails and tightly embrace the same, as will be seen in Fig.2. When the nuts are again loosened, the rails may be removed when sorequired.

In order to permit the rails to be seated in the recesses at the ends ofthe latter next to the longitudinal side pieces B and C of the frames,said pieces are cut-away opposite to said ends as at J, J, the railsthus being adapted to rest upon the bases of the recesses F, and uponsaid cut-away portions J, as said bases and portions are continuities ofeach leaves the center of the same open for purposes of ballasting,filling-in, disc. The outer transverse piece of each frame is longerthan the adjacent inner piece of the other frame, so that said innerpiece is Wholly inclosed by said outer piece, and a rail rests ingrooves on both pieces and the portion of the side piece B in line withsaid grooves.

' Having thus described myinvention, what I claim as new, and desire tosecure by Letters Patent, is I 1. A railroad tie formed of two frames,each consisting of a longitudinal piece having a transverse piece ateach end thereof, one of said transverse pieces of each frame beinglonger than the other transverse piece of the same frame, and thecontiguous transverse pieces of the frames having recesses for therails, said parts being combined substantially as described.

2. A railroad tie formed of two frames, each consisting of alongitudinal piece and parallel transverse pieces at its ends of unequallength, where the longitudinal sides of the frame are separated, and theend of one frame incloses the end of the other, the opposite crosspieces having recesses for seating the rails, said parts being combinedsubstantially as described.

3. A tie formed of recessed transverse pieces, and recessed longitudinalpieces connected therewith, the longitudinal pieces being cut away atthe ends of the recesses of the transverse pieces, said parts beingcombined substantially as described.
